Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a slide core-pulling mechanism and a mold. Background Art

[0002] It is often necessary to design structures such as holes, recesses and bosses on the outside of cast plastic products. However, if our casting mold has corresponding grooves on the side to form these structures, the plastic part will not be able to be ejected from the mold by ejection structures such as ejectors. Therefore, the slider used to form special structures on the mold must be a movable core that can move laterally, which is used to pull out the lateral slider before the plastic part is ejected from the mold, and then demold it through the ejection structure.

[0003] In the related art, a core pulling mechanism is provided on the side edge of the mold, and the core pulling mechanism includes an adjusting rod and a mating piece. The adjusting rod is connected to the upper mold and arranged facing the lower mold. The extension direction of the adjusting rod is arranged along the direction facing the outer edge of the mold. The adjusting rod is provided with a mating groove facing the mold, which is used to shape the side edge of the plastic part. The mating piece is provided with an adjusting groove facing the adjusting rod, and the adjusting rod is connected to the adjusting groove. When the mold is opened, the upper mold and the lower mold are separated, and the adjusting rod will abut against the mating piece and move the mating piece in the direction away from the plastic part to achieve the effect of rapid demolding.

[0004] However, the matching part not only has the function of shaping the plastic part with the mold, but also has the function of assisting the mold in sealing. After the pouring is completed, the matching part will have a larger contact area with the mold, and the connecting force between the matching part and the plastic part is also relatively large. It will be very difficult for the adjusting rod to separate the matching part from the plastic part, and the plastic part will easily be damaged due to uneven force. Utility Model Content

The sealing structure is penetrated between the upper shaping end 12 and the lower shaping end 21 to prevent liquid leakage. Because the upper shaping end 12, the lower shaping end 21 and the core pulling mechanism 4 are in a sealed vacuum state as a whole after the die-casting is completed, it is relatively difficult to pull out the core pulling mechanism 4. Therefore, the first slider 5 is provided with a first release portion 55 relative to the second slider 6.

When liquid is injected into the die-casting space 3 through the gate 11, the remaining gas is pressed into the exhaust groove 52, which can effectively improve the quality of the plastic part. A liquid guide portion 53 is provided at a position opposite to the exhaust groove 52 below the matching portion 51, which can be used to guide excess liquid away from the plastic part. Also in order to improve the quality of the plastic part, the first slider 5 is provided with a sliding groove 54 facing the second slider 6. In this embodiment, the sliding groove 54 is a T-shaped groove, which is mainly for the purpose of enabling the first slider 5 and the second slider 6 to be tightly connected together, and when the two slide relative to each other, there will be no problem with the overall structure to avoid affecting the quality of the plastic part. One end of the sliding groove 54 is provided at the end face of the sliding block 41 facing the limiting block 92, and the other end is provided to the interior of the first slider 5 and is provided close to the liquid guide portion 53.

[0040] Combined with reference Figures 4 to 5 In one embodiment of the present application, the second slider 6 is provided with a matching block 61 relative to the sliding groove 54, the sliding groove 54 is provided with a limiting portion facing the liquid guiding portion 53, the matching block 61 abuts against the limiting portion, the second slider 6 is provided with a sealing portion 62 facing the matching portion 51, the sealing portion 62 is provided with a drainage portion 63 relative to the liquid guiding portion 53, the drainage portion 63 is connected to the liquid guiding portion 53, and the second slider 6 is provided with a second releasing portion 64 relative to the first releasing portion 55.

The sliding groove 54 is provided with a limiting portion facing the liquid guide portion 53, and the limiting portion is used to limit the extreme position of the second slider 6, so that the matching portion 51 is relatively protruding, which is convenient for shaping the plastic part. The second slider 6 is provided with a sealing portion 62 facing the die-casting space 3 to avoid liquid leakage, and the sealing portion 62 is connected to the liquid guide portion 53, and a drainage portion 63 is provided relative to the liquid guide portion 53. While not affecting the sealing performance, excess liquid can be discharged through the drainage portion 63 to improve product quality. In order to allow the sealing portion 62 to smoothly detach from the die-casting space 3, the second slider 6 is relatively provided with a second releasing portion 64, and the inclined guide column 91 is penetrated through the second releasing portion 64.

When the mechanism is in die-casting operation, the end surface of the second release portion 64 facing the die-casting space 3 can be connected to or wrapped around the end surface of the first release portion 55 facing the die-casting space 3, so that the second release portion 64 will not block the normal operation of the inclined guide column 91, and the end of the second release portion 64 away from the die-casting space 3 is wrapped around the end surface of the first release portion 55 away from the die-casting space 3. In this way, when the upper and lower shaping seats 2 are opened, the inclined guide column 91 will preferably drive the first slider 5 to separate. When the first slider 5 is separated to a certain extent, the inclined guide column 91 will abut against the second slider 6 and drive the second slider 6 to separate, which can effectively improve the separation efficiency of the core pulling mechanism 4.
